[amibroker] Re: Finding trading range/horizontal channel, can it be done like this?
OK, here is what I have come up with. It will perform an exploration, but it will just list all the stock, not filter out the ones that are not meeting my criteria. Background; I search for the 3 highest high value for past 10 days, 10-20 days and 20-30 days. Then I want to find the smallest of these values and compare it to the highest high value of them all, if they don't deviate by more than 2%, the stock has a resistance level at that point. Same thing with the lowest low values, which will find me the support level. The problem I am facing now is that there is something wrong with finding the smallest of the Highest high values. The HHmin is just set as 1.00 and not as the value of the smallest of the 3 HHVs. I hope someone can help me with this. I think I'm close now. /* Find stocks in a trading range **/ // First find the highest high values, And lowest low values for the //3 periods; 10 days ago, 10-20 days ago, and 20-30 days ago HHA=Ref(HHV(H,10),-1); //HHV of 10 days ago (for example 33) HHB=Ref(HHV(H,10),-10); //HHV of 10 to 20 ago (for example 32) HHC=Ref(HHV(H,10),-20); //HHV of 20 to 30 days ago (for example 34) LLA=Ref(LLV(L,10),-1); //LLV of 10 days ago (for example 33) LLB=Ref(LLV(L,10),-10); //LLV of 10 to 20 ago (for example 32) LLC=Ref(LLV(L,10),-20); //LLV of 20 to 30 days ago (for example 34) //Then find the smallest value of the 3 HHVs, and the largest value of the LLVs HHmin = IIf((HHA HHB=True) AND (HHA HHC=True), HHA, HHB); HHmin = IIf((HHB HHA=True) AND (HHB HHC=True), HHB, HHB); HHmin = IIf((HHC HHB=True) AND (HHC HHA=True), HHC, HHB); LLmax = IIf((LLA LLB=True) AND (LLA LLC=True), LLA, LLA); LLmax = IIf((LLB LLA=True) AND (LLB LLC=True), LLB, LLB); LLmax = IIf((LLC LLB=True) AND (LLC LLA=True), LLC, LLB); //Then caluculate the average of these HHVs and LLVs //NOTE: this is not needed for the time being HHavg=((HHA+HHB+HHC)/3);//(for example = 33) LLavg=((LLA+LLB+LLC)/3); //(for example =28) //Then check to see if the min and max of the three HHVs and //LLVs are not deviating too much, I chose 5% as example //of maximum deviation.

Hi, A couple of things occur to me: 1.) At one point the code defines HChannel as False. Later the terminology used is hChannel. Should those be the same? 2.) Also, the statement, Filter=hChannel=True; probably should read Filter=hChannel==True;. I believe the current wording sets Filter to True but it appears that you want to set the Filter to True only when hChannel is True. Hope this helps.

Another follow up. You might want to check your code for the use of = (assignment) versus == (equal). It looks like you should be using == instead of = in several places.

[amibroker] Re: Finding trading range/horizontal channel, can it be done like this?
OK first problem I encounter when trying to write this in amibroker,
is that this doesn't work...:
HHA=HHV(H,10); //HHV of 10 days ago (for example 33)
HHB=HHV(H,10,-10); //HHV of 10 to 20 ago (for example 32)
HHC=HHV(H,10,-20); //HHV of 20 to 30 days ago (for example 34)
Any idea how to get the highest high value from, 10 days ago (not
counting today), 10 to 20 days ago and 20-30 days ago?
Is it possible in an easy fashion?
Thanks!

Then if the HHV/LLV for these timeperiods don't deviate from each

[amibroker] Re: Finding trading range/horizontal channel, can it be done like this?
Hi,
I believe that you have included one too many arguments for HHV.
Are you trying to use Ref with HHV? You can use the following
simple code to see if this helps:
HHB=Ref(HHV(C,10),-10);
AddColumn(C,Close,1.2);
AddColumn(Htest,Htest,1.2);
Filter=1;
I don't know if this will get you where you are trying to go or not
but the syntax does appear to be a problem. Others who are much more
familiar with AFL will, no doubt, be able to provide more insight.
I would also check the AFL library as I seem to recall seeing some
examples that address channels. TJ has some code there that deals
with troughs and peaks, which is somewhat related to your subject. He
has some excellent commentary included in the listing that you might
find interesting and helpful:

suitable way?..:
To find the the HHV for the last 10 days, AND the HHV for the last 10
to 20 days, AND the HHV for the last 20 to 30 days.
And then the same thing for the LLV. Do you understand what I mean?
Then if the HHV/LLV for these timeperiods don't deviate from each
other that much, then I can assume that there is resistance/support
for past 30 days at this level. I could divide the range into
more/less timeperiods also, I don't know the best number of periods,
I chose 3 to begin with.
What do you think about this approach? Do you find anything that
don't make sense about this?

give! It's highly appreciated!
[amibroker] Re: Finding trading range/horizontal channel, can it be done like this?
Hi, again.
Note that the following line should be changed to read:
AddColumn(HHB,HHB,1.2);
I switched in mid-thought in order to use your terminology. It's too
early for me to be thinking, in any case.

Hi,
I believe that you have included one too many arguments for HHV.
Are you trying to use Ref with HHV? You can use the following
simple code to see if this helps:
HHB=Ref(HHV(C,10),-10);
AddColumn(C,Close,1.2);
AddColumn(Htest,Htest,1.2);
Filter=1;
I don't know if this will get you where you are trying to go or not
but the syntax does appear to be a problem. Others who are much more
familiar with AFL will, no doubt, be able to provide more insight.
I would also check the AFL library as I seem to recall seeing some
examples that address channels. TJ has some code there that deals
with troughs and peaks, which is somewhat related to your subject. He
has some excellent commentary included in the listing that you might
find interesting and helpful:

Hi, thanks a lot for your help! It seems to work like that, thanks!
Haven't succeeded to run this because I don't seem to get my if-
statements correct either. The error message i get is Error 6.
Condition in IF, WHILE, FOR statements has to be Numeric or Boolean
type. You can not use array here, please use [] (array subscript
operator) to access array elements.. :(
Hopefully someone can solve this for me, I tried to do it in two ways
but haven't really got it right.. :(
/CODE Snippet
//Averages of three HHVs and LLVs
HHavg=(HHA+HHB+HHC/3);
LLavg=(LLA+LLB+LLC/3);
//Calculate 5% of HHV, both 5% more and 5% less
HHmin=(HHV(H,30) * 0.95);
HHmax=(HHV(H,30) * 1.05);
LLmin=(LLV(L,30) * 0.95);
LLmax=(LLV(L,30) * 1.05);
//Now check to see if the averages of the three HHVs and
//LLVs are not deviating too much from the min and max values,
//I chose 5% as example of maximum deviation.
//HHAvg is between HHV - 5% and HHV + 5%
//LLAvg is between LLV - 5% and LLV + 5%
//I tried to make this like a nested if-statement
//HChannel is set as False to begin with...
HChannel=False;
if (HHavg HHmin) {
if (HHavg HHmax) {
if (LLavg LLmin) {
if (LLavg LLmax) {
hChannel=True; }
} } }
//Finally the filter for the exploration
Filter=hChannel=True;
